10 Top Strategies to Lower E-commerce Shipping Costs in 2025

In the fast-paced UK e-commerce market, efficient e-commerce shipping cost management is key to success.

‍

With an expected growth to £177.72 billion by 2023, businesses need to optimise shipping to attract and retain customers, as 61% are likely to abandon carts if shipping fees are too high.

‍

1. How are transportation fees calculated?

‍

1.1 Package weight

‍

Most carriers, including Royal Mail, DPD, Chronopost, Mondial Relay and Evri, use the package weight to calculate logistic fees.

The rationale behind it: the heavier the package, the more it will cost.

‍

1.2 Package size

‍

Besides weight, the size of the package also plays a crucial role. Larger packages occupy more space, limiting the number of items a carrier can transport at once. 

‍

This is why carriers, including air and road transport companies like DHL, FedEx or UPS, use dimensional weight for pricing. 

‍

^{Dimensional weight is calculated using the formula (length x width x height) / 5000, measured in centimetres.} 

‍

It helps determine the shipping price based on the larger of the two weights — actual or dimensional. 

‍

Understanding how carriers are calculating shipping costs can help you optimise packaging to reduce shipping expenses.

1.3 Contents

‍

If your package contains high-value items, it's prudent to opt for additional insurance to safeguard against damage or loss. Shipping luxury items, such as expensive perfumes or designer pieces, demands extra caution.

True, the package becomes the carrier’s responsibility when the merchandise arrives at the warehouse until they are delivered to the final client. However, there is a cap on the compensations and indemnities, and they end up being fixed at their discretion.

In the event of the loss of an expensive item, it is quite likely that the carrier’s compensation policy will partially cover the damages. Not only will you not recover the full value of your package, but you will also be obliged to send a new product to the client at your expense. 

‍

1.4 Delivery speed

‍

Standard delivery will have a lower price than express delivery.

As you know, customers are becoming extremely demanding when it comes to delivery time. They expect their package to be delivered within 48 hours.

Express shipping entails additional costs that are often negatively perceived by customers. Your challenge will be to educate them on the benefits of standard delivery: less expensive and more environmentally friendly. This will help you both cut costs and improve your brand’s image.

‍

1.5 Additional costs to keep in mind

‍

Shipping costs are not just about the transportation itself. 

They also include all the expenses involved in preparing the package, such as storage, picking, and packaging (including personalisation). Finally, if you are shipping internationally, you will have to pay certain taxes or duties.

‍

10 strategies to help you optimise your shipping costs 

‍

8.1 Multi-carrier approach

‍

Employing a variety of shipping carriers offers flexibility and access to different shipping methods. For domestic shipping within the UK, carriers like Royal Mail are popular for their reliability and trust. For e-commerce businesses, diversifying carriers means potentially accessing more competitive options that cater to various customer needs.

8.2 International shipping policies

‍

Navigating international shipping has become more complex post-Brexit, with additional customs duties and regulations. Clear communication of shipping policies and fees is essential for expanding global reach while maintaining customer trust.

‍

‍

8.3 Balancing free shipping with financial health

‍

Offering free shipping is an effective strategy to attract customers, but it must be balanced with the business's financial health. Setting minimum order values for free shipping can be a sustainable approach. 

Continuing to manage it smartly is crucial. This can involve promotional strategies like limited-time free shipping offers or loyalty program benefits, which can boost customer acquisition and retention while managing cost impact.

‍

8.4 Efficient delivery service

‍

Ensuring a fast and accurate delivery process, including efficient pick, pack, and ship operations, is essential for meeting customer expectations. Timely delivery enhances customer satisfaction and loyalty, directly influencing repeat business and positive reviews.

‍

8.5 Flexible delivery choices

‍

Offering a range of delivery options, including next-day and standard shipping, allows customers to choose based on their needs and urgency. This flexibility is especially important in today's market, where delivery time can be a deciding factor for many online shoppers.

‍

8.6 Leveraging technology

‍

Incorporating technology to streamline the shipping process is vital. This includes the use of automated systems for generating shipping labels, tracking deliveries, and reducing shipping errors. For instance, at Bigblue we use algorithms to detect invalid addresses, preventing shipping errors and ensuring efficiency.

‍

8.7 Understanding consumer behaviour

‍

Recognising patterns like the high rate of online returns (54% in the UK) helps in optimising the shipping process. An efficient returns process not only improves customer satisfaction but also helps in retaining loyalty.

‍

8.8 Good customer service

‍

Be ready to help customers with any questions or problems they have with shipping. This builds trust and loyalty.

8.9 Data-driven shipping decisions

‍

Using data analytics to understand shipping patterns, peak times, and customer preferences can lead to more informed and cost-effective shipping decisions. This approach enables businesses to optimise their shipping options and costs based on actual customer behaviour and preferences.

‍

8.10 Smart packaging and sustainability

‍

Adopting smart packaging solutions that match product size helps reduce shipping rates and waste. 40% of UK shoppers are willing to pay more for carbon-neutral shipping, signalling a shift towards eco-friendliness in consumer preferences.

Offering eco-friendly shipping options appeals to environmentally conscious consumers and can differentiate a brand in a competitive market.

‍

Hire a logistics provider to reduce shipping costs

‍

Logistics are incredibly time-consuming. You should be investing your energy in growing your business.
